Abstract

PURPOSE: An automatic material conveyer system is provided to deliver efficiently a lot from a stocker by operating lots in batch units. CONSTITUTION: A lot stored in a stocker(10,112) is transferred automatically to a device(14,116) by connecting directly a stocker(10,112) with a robot(18,120). A delivery process of batch units is performed in the stocker(10,112) by a first-in first-out method. A system for managing the device(14,116) and the robot(18,120) is separated from a system for managing the stocker(10,112). The composition of the batch is generated from other system on the basis of stored lots. The composition of the batch is transferred to the system for managing the stocker(10,112). The lot composed in the system is transferred to the system for managing the stocker(10,112). The delivery process is performed according to a storing state of the stocker(10,112).

Description

Logistics automated return system {SYSTEM FOR RETURNING PRODUCT AUTOMATICALLY}

The present invention relates to a semiconductor facility, and more particularly to an automated logistics transfer system.

Conventionally, a process is performed by loading a lot from a stocker or loading a lot directly moved by a worker to a facility in order to load a lot into a facility. However, in the new line (robot) and the stocker is directly connected to the robot shipped from the stocker to move the robot to move directly to the facility without the operator's movement.

In the above situation, several lots must be loaded into the plant in batches and, if multiple batches are present, they must be shipped from the batch of the ordered batch first. However, the existing automatic return system does not work in batches because the goods are received and shipped in lots.

In the present invention, the stocker and the robot are directly connected to each other without the worker moving manually to load the lot into the facility, so the lot stored in the stocker is directly moved to the facility. Thus, the stalker must be shipped in batches based on first-in, first-out. However, the existing automatic return system is not a batch (batch) unit, but the lot is received and shipped in batches, so if there are multiple batches can not be shipped normally the batch that was first instructed. Therefore, the present invention has been made to check the status of the stocker, the order between batches and the order of lots in the batch so that the optimal lot can be shipped from the stocker.

The present invention is to provide an automated logistics return system that optimally manages the lot to be shipped from the stocker.

The present invention has been proposed to solve the above-mentioned problems, the automatic logistic conveying system is a system for operating a lot, the lot is operated in batch units (batch), characterized in that the batch consisting of the batch can be transported sequentially It is done.

(Example)

An embodiment of the present invention will be described in detail with reference to FIG. 1.

The novel logistic automated return system of the present invention checks the order of the lots to optimize the lot being shipped from the stocker.

1 is a view showing an automatic logistics transport system according to a preferred embodiment of the present invention.

The configuration of the batch may be made based on the hardware configuration of FIG. 1. In addition, depending on the sequence of batches configured and the equipment selected, they must be released from the stocker by first-in, first-out. The system for managing facilities and robots is separate from the system for managing stockers. The batch configuration is created on another system based on the lot stored in the stocker and transferred to the stocker managing system. The batches that make up will be unaffected by the number of lots that make up one batch if they consist of one to six lots. The parent system delivers the configured lot to the stalker system at the same time and responds to the availability of the stalker.

The batch configuration method and stocker release will be described by way of example.

As for the number of lots stored in the stocker, the stocker 1 has a total of 10 lots from L10.1 to L19.1. Stocker 2 also stores 10 lots from L20.1 to L29.1.

If you look at the batch configuration and shipping order, it doesn't matter which stocker the lot is stored in, and the batches stored in stocker 1 and stocker 2 are batches of equipment 1 or equipment 2. It is important that it can be constructed. Describe the configurations one by one.

The first configuration is batch 1 and batch 2, batch 1 (equipment 1) consists of lots of L10.1, L11.1, L12.1 and batch 2 (equipment 2) is L20.1, L21.1, L22 It consists of lots of .1s. In this configuration, stocker 1 and stocker 2 work simultaneously.

Stalker 1: L10.1 → L11.1 → L12.1

Stalker 2: L20.1 → L21.1 → L22.1

That is, the L10.1 lot of stocker 1 and the L20.1 lot of stocker 2 are made simultaneously and the next lot is made at the same time.

The second configuration consists of batch 1 (equipment 1) with lots of L10.1, L11.1 and L20.1 and batch 2 (equipment 2) with lots of L21.1, L22.1 and L12.1. . In this configuration, only part of Stocker 1 and Stocker 2 are operated simultaneously.

Stalker 1: L10.1 → L11.1 → L12.1

Stalker 2: L20.1 → L21.1 → L22.1

That is, the lot L10.1 of the stocker 1 and the lot L20.1 of the stocker 2 proceed at the same time, but the stocker 2 is paused in the next step and the work is performed again in the next step.

The third configuration consists of batch 1 (equipment 1) with lots of L10.1, L11.1 and L12.1 and batch 2 (equipment 2) with lots of L20.1, L21.1 and L22.1. In this configuration, the work in batch 2 takes place after the work in batch 1 is completed.

Stalker 1: L10 → L11.1 → L12.1

Stalker 2: L20.1 → L21.1 → L22.1

That is, during the operation of the stocker 1, the operation may be performed in the stocker 2 at the same time, but wait for the stocker 2 according to the batch order.

In the fourth configuration, batch 1 (equipment 1) consists of lots of L10.1, L20.1, and L11.1 and batch 2 (equipment 2) consists of lots of L12.1, L21.1, and L22.1. In this configuration, the work in batch 1 and the work in batch 2 are performed at the same time.

Stalker 1: L10.1 → L11.1 → L12.1

Stalker 2: L20.1 → L21.1 → L22.1

That is, stocker 2 has to wait to work on batch 2 until the work on batch 1 is complete.

The storage of data in the present invention allows for the organization of items required for placement in order to store placement information and to have a structure pointer of the next arrangement in the placement structure. Structures information about Stocker 1 and Stocker 2 and has a structure pointer to placement within the Stocker structure. When the batch instruction is received from the host system, the stored stocker information of the batch lot is retrieved and the batch information of the batch pointer in the stocker structure is stored. The next lot is stored in the next batch structure in the batch.

In the present invention, the work order to the stocker selects the most suitable lot each time the work is completed in the stocker. The selection condition is, first, take a stock pointer of the stocker and check if there is a batch that has been instructed in the same equipment among other stockers. Second, if no batch has been first ordered on the same plant, the lot is shipped. If no batch has been first ordered on the same plant, the lot is shipped. Third, if there is a batch indicated first in the same facility, it moves to the next batch pointer. Repeat the first, second, and third operation to check if there is a suitable lot and order it. When selecting a job according to the selection condition, the job proceeds sequentially from the first lot of the batch that has been first instructed.

The present invention has the effect that the optimal lot can be released from the stocker by checking the status of the stocker, the order between the batches and within the batch.
